The outage investigation has not progressed due to mutual accusations and lack of information.

A panel of European experts investigating the blackout denounced the government’s lack of cooperation with the power companies, while the president of REE pointed the finger at the “traditional power generation groups” and the opposition media denounced the government’s “deceptive behavior”.

More than a month after the blackout in the Iberian Peninsula, the cause of which is still unknown — the most common assumption is that it was a power surge — forces are still using the event to “report” on it.

The American newspaper The Wall Street Journal linked the blackout to renewable energy on Tuesday, as did the British newspaper The Daily Telegraph a week earlier. In an opinion piece, Danish professor Bjørn Lomborg noted that the Spanish government continues to invest in renewable energy, knowing that solar and wind power are “unreliable”. He also warned that future solutions to avoid continuous blackouts would be “costly”.

In an interview with La Noche en 24h on Tuesday, Beatriz Corredor, president of the Spanish electricity company REE, said: “There are no short circuits, inertia, computerized systems, lack of reserves or overvoltage in the transmission grid. The analysis shows that the voltage control of the conventional generation groups does not comply with the parameters set by the National Market and Competition Commission (CNMC).”

As La Vanguardia reported this Wednesday, on May 28, the president of the European grid operator, National Grid Europe (ENTSO-E), and its board of directors, which was part of the panel of experts that investigated the April 28 blackouts in Spain and Portugal, sent a letter to the Spanish government and the European Commission asking for assistance and warning them of the lack of major power companies’ access to data that could reveal the truth about the events Cooperation. The letter noted that the companies “claim that they are legally obliged to comply with confidentiality requirements”.

The agency noted that “it is necessary to determine whether known outages in the system are the cause or the result of the problem. The facility may have been disconnected for safety reasons after the oscillations were detected, or the oscillations may have been caused by a sudden, foreseeable power failure. For this reason, at this stage of the investigation, we must go down to microsecond details, information that is only available to each power plant, each plant owner or other system stakeholder.”

For its part, Cinco Días explained that a letter sent by ENTSO-E to Sara Aagesen, Third Vice-President and Minister of Ecological Transformation, stated that “Red Eléctrica has recently informed us of the unwillingness of a third party to share the relevant data, which could lead to delays in the Panel’s investigation.”

Aelēc, an association representing power companies such as Endesa, Iberdrola and EDP, has applied to be one of the stakeholders in the commission investigating the causes of the blackouts. The association also recently requested that “the scope of the investigation should cover the extreme and widespread voltage fluctuations that occurred in the grid on the morning of April 28 and in the days leading up to the 22nd and 24th”. This refers to two voltage fluctuations in the Iberian power system detected on the day of the blackout. Ogson, who volunteered to appear at a congressional hearing in mid-May, said the losses were caused by reasons unrelated to the transmission grid, namely its operator, Red Eléctrica. “The root cause of these outages may lie in the power plants themselves or in grids that are not managed by Red Eléctrica,” the minister said, referring to the distribution grids managed by Endesa, Iberdrola, Naturgy and EDP.

Meanwhile, Beatriz Corredor, speaking at the Iberoamerican Business Conference organized by Ceapi in Seville on Wednesday, said that “no fault” in Red Eléctrica had led to the accident, and she ruled out that She also ruled out the possibility of facing any form of compensation “as of today”.
